Original application led. Inch 7., 191W,v Serial To all whom 'it comem:

Be it known that I, WILLIAM J. BALDWIN, a citizen of the United Statesof America, and a. resident of the borough of Brooklyn, in the city ofNew York, State'of New `lork, have invented certain new and usefulImprovements in Apparatus for Separating Heavy Particles from Air andotherl Gases, of which the following is a specification.

This invention relates toimprovements in apparatus for separating heavyparticles from air and other gases; the present application being adivision of my application for improvements in the art of separatingvsuch particles from air and other gases, filed in the United' StatesPatent Office, March 7, 1907, Serial Number 361,099 and new pending. Inmy said application', Serial' Number 361,0?9, I set forth my improvedprocess for effecting such separation, and the presentapplicationrelates particularly to the preferred forms of apparatus for applyingsaid process.

The apparatus is intended to be used for the separation of various heavy4materials from air and other gases,v as unconsnmed carbon from smoke.dust from air, sawdust from the air of factories, tar and other heavymaterials from coal'l gas and other gases; and in general the apparatusis intended to be applied to the se aration of lheavy materials from airand ot er gases in all cases in which lthe process can be used.

'leferring to the drawings which illustrate several modifications ofapparatus by which the said process may be performed, in order toindicate the essential features of such apparatus, which essentialfeatures are,

: a. transverse vertical section and elevation of a modification of theap aratus in which the screen is :formed with s its, and Fig. 4 is aslde elevation and sectlon of thesame; Fig.

5 being an enlarged detail of a 'part of said.`

screen. Fig. 6 is a transverse vertical section and elevation of thepreferred form ofY the apparatus, in "which the screen is provided witha slot, and Fig. 7 is aside eleva-y tion and section of the same.

Referring to Figs. 1 and 2, the device is specimens of amersrate-nt.

Set in; achamber A, which may be a casing as shown in the drawings, ormay be a room in: a build-ingv or any other suitable chamber. saidlchamber A is a suitable fan or blower D on a shaft d, and driven at hi`h velocity from a prime motor not shown. t a: suitable distance'fromsaid fan D within said' chamber A is a screen E, which: in thismodification is wire mesh suitably supported in said chamber A, and themesh of said screen E is suiiiciently large to lpermits theheavy'part'icles to pass through. The inlet B connects with the s acewithin said screen E. and a' conduit connectedi with any suitablesupply, and controlled by a valve g', delivers a suitable liquid, suchIas water, oil, steam which on condensation becomes water,

or other suitable liquid into the gas which conbains-the heavymaterials.` C ls'a discharge for the gas after 4the separation of theheavy materials and connected with the space witir- A in said, screen'E, and I" prefer to` leave a smallspace between the Wall of saidIdischargel C and said screen E, as seen at" le, Fig. 2. Said inletB ispreferabl 'connected with'saidlchamber A by a pipe controlled by adamper 71., and I prefer to also provide said chamber A with anv outleti controlled byI a damper j, which outletmay be led to the dischar e Cor to any' other desired place. Sai chamber A may be rovided with aconnection K to any desire collecting Vessel orchamber, for collectingthe heavy -materials which have been separated `from the gas.

The operation is as follows The atmospheric alr or other gas containingthe heavy materials enters the screen E by the inlet B,

and the materials, the mixture being termed mud by me for sake ofbrevity of description. This mud is projected against the screen E bythe centrifugal effect of the fan D,'and much of the mud flies directlythrou h the meshes of said screen. What mu does not' ily through willsoon be forced through by the pressure ofthe gas,

and of course, can not return into the gas, -because said screen E andthe outward pres- 11o will pass through. the screen E together with themud but much of the gas will not pass there through, but will iow aroundthe screen E` and out at the discharge C, being freed from the heavyparticles which, as hereinabove stated, have passed through the screen Eas mud. That portion of the gas which. passed through the screen withthe mud soon becomes freed from the mud because the latter drops downinto the aforesaid receptacle, or trickles down the said screen E, andthis portion of the air may be delivered by the pipe H to the inlet B,to be again acted on by the apparatus, or

may be sent out by outlet into the discharge C, or to any other desiredplace. By regulating the opening of the dampers k, j, I can alsoregulate the quantity of air which will pass through the screen E.

The .arrangement of the parts, and the operation of the apparatusillustrated inl Figs. 3, 4 and 5, is substantially similar to thatdescribedc But the screen E is now formed with slits 0 between inclinedlips or slatsp, which may be conveniently formed by cuttin suitableslits in the metal of which Screen E is made, and then bending in theedges as indicated.. 0r said slats may be separate pieces attached tothe ends of the screen E; and I find that the Ainclination of said slatsp is useil in certain cases in deecting the mud through the screen.,

Referring to Figs. 6 and 7, the screen E2 is preferably made in twoparts, s and t, for convenience of manufacture, although it might bemade in one piece, and with inclined sides to give direction tothe heavyparticles, anda slot v in said screen E2 extends around the greater partthereof, as indicated in Figs. 6 and 7. I find that eaaeoa sure of thegas preventu Some of the 'as screens of this shape and construction arevery effective with certain classes of rnaterials, producing an almostperfect separation of the heavy materials from the gas.

It will be evident from the foregoing description, that the screen maybe formed of numerous materials and of different shapes andconstructions, and therefore by the term screen as used in thisapplication, I intend to cover any suitable diaphragm, Wall, partition,or separating member, by which the separation of the heavy materialsfrom gas can be effected.

New having described my improvements, I claim as my invention.

l. The combination in apparatus for sepa rating heavy material fromgases, of a stationary chamber, a, blower therein, a perforate screen inthe path of the high velocity gas, an inlet thereto, a conduit adaptedto deliver liquid into said gas, a discharge for the gas from the insideof said screen, and a connection from the space outside said screen tosaid inlet, substantially as described 2. The combination in apparatusfor separating heavy materials from gases, of a stationary chamber, ablower therein, a perforn ate screen in the path of the high velocitygas, an inlet te said chamber, a .conduit adapted to deliver liquid intothe gas, a discharge for gas from the space wlthin said screen and adischarge for gas from the space Without said screen, and means forcontrolling either of said discharges, substantially as described.
